从模式窗口打印的jquery

printing jquery

Kung Fu Ninja · 技术社区 · 16 年前

 // Create a jquery plugin that prints the given element.
jQuery.fn.print = function(){
// NOTE: We are trimming the jQuery collection down to the
// first element in the collection.
if (this.size() > 1){
    this.eq( 0 ).print();
    return;
} else if (!this.size()){
    return;
}

// ASSERT: At this point, we know that the current jQuery
// collection (as defined by THIS), contains only one
// printable element.

// Create a random name for the print frame.
var strFrameName = ("printer-" + (new Date()).getTime());

// Create an iFrame with the new name.
var jFrame = $( "<iframe name='" + strFrameName + "'>" );

// Hide the frame (sort of) and attach to the body.
jFrame
    .css( "width", "1px" )
    .css( "height", "1px" )
    .css( "position", "absolute" )
    .css( "left", "-9999px" )
    .appendTo( $( "body:first" ) )
;

// Get a FRAMES reference to the new frame.
var objFrame = window.frames[ strFrameName ];

// Get a reference to the DOM in the new frame.
var objDoc = objFrame.document;

// Write the HTML for the document. In this, we will
// write out the HTML of the current element.
objDoc.open();
objDoc.write( "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">" );
objDoc.write( "<html>" );
objDoc.write( "<body>" );
objDoc.write( "<head>" );
objDoc.write( "<title>" );
objDoc.write( document.title );
objDoc.write( "</title>" );
objDoc.write( "<div id='viewNotes'></div>" );
objDoc.write( "</head>" );
//objDoc.write( this.html() );
objDoc.write( "</body>" );
objDoc.write( "</html>" );
//objDoc.close();

formData = 'cmid=C93F52DCE21ABBD5';
$.ajax({
    url: 'ajax/ajax_get_notes.cfm',
    type: 'GET',
    data: formData,
    cache: false,
    success: function(result) {
        $('#viewNotes').html(result);
    },
    error: function(xmlHttpRequest, status, err) {
        $('#viewNotes').html('error:'+err);
    }
});     

// Print the document.
objFrame.focus();
//objFrame.print();

// Have the frame remove itself in about a minute so that
// we don't build up too many of these frames.
setTimeout(
    function(){
        jFrame.remove();
    },
    (60 * 1000)
    );

alert('i am here');
}

我做错什么了?有没有更好的方法来实现这一点?

我发现有几件事不对。

首先,不创建iFrame,因为没有结束标记。其次,iFrame从未添加到页面中。第三,jFrame CSS没有正确声明(应该是'jFrame')。第四,html标记的顺序不对。

我想你可以这样做:

var strFrameName = ("printer-" + (new Date()).getTime());

// Create an iFrame with the new name.
var jFrame = $( "<iframe name='" + strFrameName + "'><div id='viewNotes'></div></iframe>" );

// Get a FRAMES reference to the new frame.
var objFrame = window.frames[ strFrameName ];

// Get a reference to the DOM in the new frame.
var objDoc = objFrame.document;

// Write the HTML for the document. In this, we will
// write out the HTML of the current element.
objDoc.open();
objDoc.write( "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\"  \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">" );
objDoc.write( "<html>" );
objDoc.write( "<head>" );
objDoc.write( "<title>" );
objDoc.write( document.title );
objDoc.write( "</title>" );
objDoc.write( "</head>" );
objDoc.write( "<body>" );
objDoc.write( jframe );
objDoc.write( "</body>" );
objDoc.write( "</html>" );
//objDoc.close();

formData = 'cmid=C93F52DCE21ABBD5';
$.ajax({
   url: 'ajax/ajax_get_notes.cfm',
   type: 'GET',
   data: formData,
   cache: false,
   success: function(result) {
       $('#viewNotes').html(result);
   },
   error: function(xmlHttpRequest, status, err) {
       $('#viewNotes').html('error:'+err);
   }
});     
//print

我最终实现了不同的目标。我创建了另一个名为printNotes.cfm的页面,它类似于notes模式窗口。我在模式窗口的“可打印版本”按钮上附加了一个window.open事件。单击后,将启动printNotes.cfm,此页面将通过ajax加载注释。在printNotes.cfm中,有一个打印机按钮,单击后会触发window.print()事件。

它就像一个符咒。

谢谢
